Plug in filler for unused port

[gregarneson]

Currently the 3M-50 has one open plug in port and if you look close can see the opening was for the cabling.
Is there and option to purchase a dummy port or filler to close this opening?

Radiothermostat does have blanks, try the web site.

better yet, call their support number, talk to the voice mail, leave your shipping address and the number of modules you need and a few days later you'll get the empty modules in the mail.

Calling for the empty module is the best way - since the Radiothermostat web site appears to sell them only in quantities of 250 pieces, for $250.00!

Lbendlin is correct, call us and we will send you the blank.
